D-link DEM-211 is 1310nm wavelength, Duplex D-link optical transceiver,through LC connector,transmitting distance can reach up to 2km .

Cozlink provide CZT-P3103-02D (in stock) compatible optical transceiver using FPlaser,Sold in eBay and amazon,we have fully stocked,high production efficiency and fast delivery time.

All of Cozlink products are 100% tested , and can be completely applied in Ethernet、Fibre Channel network devices, such as switches and routers.

If you want to get latest product datasheet or don’t know how to buy it, please feel free to contact our service online.

(Note:Class 1 laser output power is less than 0.4mW,it won’t be harmful to eyes,we can ensure the safe in design.)(with DDM function can help system management to predict the life of optical transceivers, isolate system faults and verify the modules compatibility in the site installation.

The SFP transceivers are high performance, cost effective modules supporting 155Mbps data-rate and 2km transmission distance with SMF.The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
